horse brasses, worth anything?

[dazwalsh]

In my mum's loft from previous owner I have found a box of over 200 vintage looking solid horse brasses, all various styles and themes from star signs to dickins characters and countries

I didn't even have a clue what they were until I Googled them but are they likely to be worth anything?, are collectors few and far between or is there a good want for these?

Also I didn't know what forum to throw this in so H,G & DIY it is.
